G&D DVIVision · 29 Configuration Optimising the video image The video signal is usually transmitted between the computer module and the user module in a compressed way. Thanks to this compression, the image on the console monitors are normally displayed without losses and judders. The video data to be transmitted and the preset video settings can cause the following effects. Tearing: The monitor image consists of two subsequent frames that are partly dis- played. The lower part of the image shows a part of the old frame, the upper part shows a part of the new frame. At the point where both frames touch, the image appears to be “torn”. NOTE: The HDIP mode (High Dynamic Image Processing) prevents the tearing effect and provides the best image quality even for moving images. Studdering: The number of transmittable pixels is limited by the transmission band- width. If you have selected a high resolution and the image contents change fast, some image may be skipped. The video image may seem jerky. By reducing the colour depth to 18 bits, you can maximise the number of pixels to be transmitted. Depending on the image contents, this may cause slight colour gradiations. Latencies: The additional processing of the video signal cuase a short latency in the HDIP mode. This latency may be noticed during fast mouse movements. Deactivate the HDIP mode to avoid such latencies. Use the setup menu to optimise the video image for each video channel. Optionally, you can use the setup keys to switch between the following profiles that apply to all video channels: PROFILE FEATURES Best video quality (Default) Accelerated desktop Accelerated video images Best performance 30 · G&D DVIVision best video quality maximum colour depth short latency no tearing high video quality maximum colour depth short latency tearing possible highest image refresh rate reduced colour depth short latency no tearing highest image refresh rate reduced colour depth shortest latency tearing possible SETTINGS HDIP: on Colour depth: 24 bit HDIP: off Colour depth: 24 bit HDIP: on Colour depth: 24 bit HDIP: off Colour depth: 24 bit Configuration Setup mode How to change the settings to optimise the video quality: 1.

Using the noise filter By default, the computer module analyses and compresses the computer’s incoming video signal and transmits it to the user module. Due to this compression, the data volume to be transmitted can be considerably reduced. In order to apply the compression, the image segments in the frames must not be changed. The device drivers of some graphics cards produce image noises in the video signal: The colour values of frames the user perceives as evenly coloured differ slightly. NOTE: The frames’ colour values also change for “fixed images”. As a result, the compression cannot be applied and all frames of the video signal are transmitted. Due to the missing compression, a high-resolution video signal of a computer with such a device driver leads to a large data volume that is transmitted between computer module and user module. This might affect the performance of the DVIVision system. Activate the low or high noise filter level if you experience performance losses. This way, the colour values are adjusted and the compression is possible. NOTE: With Multichannel variants, the selected noise filter level applies for all video channels. 36 · G&D DVIVision Enhanced configuration settings Setup mode How to change the noise filter level: 1.

Support of any resolution IMPORTANT: Display modes that support interlace are not supported by the DVIVision system! The DVIVision system generally supports all resolutions that can be transmitted through a single link interface according to the DVI specification 1.0. This restriction mainly affects the pixel rate, which can reach from 25 MHz to 165 MHz. Therefore, resolutions between 640 × 480 pixels at 60 Hz and 1600 × 1200 pixels at 60 Hz are possible for the common timing standards by VESA DMT and VESA SMT. 1920 × 1200 pixels at 60 Hz is transmitted according to VESA CVT-RB. Almost any refresh rate and resolution within the technical constraints are possible. The available display modes are largely dependent on the graphics card, the graphics driver, the operating system and the connected monitor. The video data that are transmitted from the computer to the computer module (DVIVision-CPU) are transferred to the monitor of the remote console with the same timing. The signal’s frequency and display position at the computer module therefore correspond to those of the graphics output. G&D DVIVision · 45 Further information NOTE: While generating the video signal, some graphics cards differentiate between digital and analog output. Such graphics cards generate digitally output image signals with partly non-standardised timings. Such timings do not comply with the monitor’s default to reduce the frequencies of the digital signals. Normally, this does not affect the DVIVision system and the digitally connected displays. Due to the non-standardised timing, analog monitors might not be able to display the image size and the image position properly. 46 · G&D DVIVision Status displays Status displays The LEDs on the front panel of both the computer module and the user module enable you to control the operational status of the DVIVision system at any time.
